pec-37-73.tnt2.f.uunet.de thinks that the @recipientdomain is not theirs, so concludes it's a relay attempt. I bet your alleged staff person needs to do SMTP AUTH or equivalent on pec-37-73.tnt2.f.uunet.de. btw, your predecessor @science-int.co.uk brought us some interesting problems, too. :)) Len http://MenAndMice.com/DNS-training http://BIND8NT.MEIway.com : ISC BIND 8.2.4 for NT4 & W2K http://IMGate.MEIway.com : Build free, hi-perf, anti-abuse mail gateways Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
